8. Cov tub yees R717:
Ammonia yog feem ntau siv nruab nrab siab nruab nrab kub tub yees.Ammonia tus qauv ntawm cov khoom kub yog 77.7 ℃, evaporating kub ntawm 33.3 ℃, lub condensing siab feem ntau ntawm chav tsev kub yog 1.1 ~ 1.3 MPa, txawm tias lub caij ntuj sov txias dej kub li siab. Raws li 30 ℃ tsawg dua 1.5 MPa.Nws yog tsuas yog siv nyob rau hauv loj industrial tub yees thiab coj mus muag tub yees.
Ib qho yooj yim kom tau, tus nqi qis, nruab nrab siab, chav tsev loj txias, siab exothermic coefficient, yuav luag insoluble hauv roj, me me khiav tsis kam, yooj yim mus nrhiav tau thaum to.Tab sis nws muaj irritating tsw, lom, hlawv thiab tawg, thiab muaj corrosive los ntawm tooj liab thiab tooj liab alloys.
9. Cov tub yees R290:
R290, propane, yog ib qho kev tiv thaiv ib puag ncig tshiab refrigerant.Mainly siv rau hauv nruab nrab cua txias, cua sov twj tso kua mis cua txias, tsev neeg cua txias thiab lwm yam me me refrigeration khoom.High purity R290 yog siv raws li kub sensing khoom.Qhov superior thiab thawj chav kawm ntawv R290 yuav ua tau. siv los ua cov tub yees los hloov R22 thiab R502, sib xws nrog cov txheej txheem qub thiab cov roj lubricating, rau lub hauv paus cua txias, cua kub twj tso kua mis cua txias, cua txias hauv tsev thiab lwm yam khoom siv tub yees me me.
Cov kev sim qhia tau hais tias tus nqi perfusion ntawm R290 nyob rau hauv tib lub kaw lus ntim yog li 43% ntawm R22.Vim tias cov cua sov latent ntawm vaporization ntawm R290 yog kwv yees li ob npaug ntawm R22, cov refrigerant ncig ntawm lub tub yees siv R290 tsawg dua. Siv R290 refrigerant, lub zog txuag tus nqi tuaj yeem ncav cuag 10-35%.The R290 "inflammable thiab explosive" tsis raug mob tuag taus.R290 tuaj yeem sib xyaw nrog huab cua los ua qhov sib xyaw tawg, uas yog qhov txaus ntshai ntawm combustion thiab tawg hauv lub xub ntiag ntawm qhov chaw tshav kub thiab qhib hluav taws.
1.Evaporation siab dua
Lub evaporation siab yog siab dua: yog hais tias lub evaporation siab ntawm lub tub yees yog qis dua lub atmospheric siab, huab cua yog yooj yim rau nkag mus rau hauv lub system thiab lub system yog tsis yooj yim sua.Yog li ntawd, nws cia siab tias qhov evaporation siab ntawm cov tub yees ntawm qhov kub qis tuaj yeem siab dua qhov siab ntawm atmospheric.
2.Lub latent cua sov ntawm evaporation yog ntau dua
Lub latent cua sov ntawm vaporization yog ntau dua: lub latent cua sov ntawm vaporization ntawm lub tub yees yog ntau dua, qhia tau hais tias ib tug loj npaum li cas ntawm tshav kub yuav absorbed los ntawm kev siv tsawg coolant.
3.Qhov kub tseem ceeb yog siab dua
Yog tias qhov ntsuas kub tseem ceeb yog siab, qhia tau hais tias cov tub yees txias coagulation kub siab, cov tub yees tuaj yeem txias los ntawm kev siv huab cua los yog dej kom ua tiav cov txiaj ntsig ntawm condensation liquefaction.
4.Lub condensation siab yog qis dua
Lub coolant siab tsis tshua muaj: qhov txias siab yog tsawg, qhia tau hais tias lub tub yees yuav ua tau liquefied nrog tsawg siab, thiab compression piv ntawm compressor yog me me, uas yuav txuag tau lub horsepower ntawm lub compressor.
5.Lub solidification kub yuav tsum tsawg
Lub freezing kub yog tsawg: lub freezing point ntawm lub coolant yog tsawg, txwv tsis pub cov coolant freezes nyob rau hauv lub evaporator thiab yuav tsis tau circulated.
6.Cov roj coolant yog me dua qhov ntim
Qhov tshwj xeeb ntim ntawm cov roj coolant yog me dua: qhov me me ntawm qhov tshwj xeeb ntim ntawm cov roj coolant, qhov zoo dua, qhov me me ntawm lub compressor tuaj yeem txo tus nqi, thiab cov yeeb nkab nqus thiab cov yeeb nkab tso tawm tuaj yeem siv cov yeeb nkab me me.
7.Liquid coolant muaj qhov ceev dua
Qhov siab dua qhov ceev ntawm cov kua coolant, siab dua qhov ceev ntawm cov kua coolant, qhov me me ntawm cov yeeb nkab yuav ua tau.
8.Soluble nyob rau hauv khov roj
Soluble hauv cov roj khov: Soluble hauv cov roj khov: lub kaw lus tsis tas yuav nruab cov roj cais.
9.Chemical stability
Chemical stability: evaporation kub yuav txawv nrog kub hloov, xws li evaporation kub ntawm cov dej khov tshuab yog 0 ~ 5 ℃, txias nyob rau hauv lub tub yees lub voj voog system, txias xov xwm tsuas yog hloov lub cev, tsis muaj tshuaj hloov, tsis decomposition.
10.Tsis muaj corrosive
Lub latent cua sov ntawm evaporation yog loj: tsis-corrosive rau hlau thiab hlau, thiab ammonia corrosive rau tooj liab. Zoo rwb thaiv tsev, txwv tsis pub nws yuav ua puas lub compressor lub cev muaj zog rwb thaiv tsev, yog li ammonia yuav tsum tsis txhob siv nyob rau hauv kaw compressor, thiaj li tsis txhob sib cuag ncaj qha. nrog tooj liab.
11.Non – toxic non – combustible non – explosive
12.Tsis txhob ua phem rau ib puag ncig
